Interstate 80 Freight Corridor Analysis: Current Freight Traffic, Trends and Projections for WYDOT Policy-makers, Planning, Engineering, Highway Safety and Enforcement. Final Report

摘要

The first phase of the study involved interviewing approximately 2,000 truck drivers over a 180-day period between September 2007 and March 2008 using a roadside intercept survey. Survey locations were the Cheyenne Port of Entry for westbound traffic and the Evanston Port of Entry for eastbound traffic. The survey identified the business entity, driver demographics, origin and destination, type of load, type of rig and other information. In general, drivers were satisfied with the condition of the I-80 facility but did identify several deficiencies. Over 30% of eastbound and westbound trucks were carrying food products. The Salt Lake City/Ogden area emerged as a major inland western freight hub. The highest number of origin-destination pairs was between Chicago and Salt Lake City/Ogden. Approximately 25% of respondents were under some type of time penalty arrangement which was most commonly associated with hauling food products. Over 2,000 origin-destination pairs by product category were loaded into a GIS database and analyzed. Maps showing these freight patterns are presented in Chapter 4. Results from this analysis were used in building freight growth scenarios in the second phase of the study. The second phase of the study examined numerous factors influencing future truck traffic volumes across Wyoming.
